To play source with the digital sound field processor

1	Follow the step 1, 2, 3, 4, and 5 shown in
	“OPERATION” on page 13.

2	Select a desired program suitable for the source.

PRO LOGIC

The corresponding indicator will illuminate.

3 If desired, adjust the delay time and the output level of each speaker. (For details, refer to the corresponding descriptions on this page and the next page.)

Note

If you prefer to cancel the selected program, press the OFF switch. The sound will be the normal 2-channel stereo without surround sound effect.

Adjustment of DELAY TIME

You can adjust the time difference between the beginning of the source sound and the beginning of the effect sound with the DELAY TIME control.

The DELAY TIME control is effective with all programs. By applying more or less delay, sound effects, background noise, and ambient noise coming at you from the rear speakers can be enhanced or subdued for extra effect.

1 PRO LOGIC: from 15 to 30 milliseconds (Preset value: 20 milliseconds)

2ENHANCED: from 15 to 30 milliseconds

(Preset value: 20 milliseconds) 3 CONCERT VIDEO: from 1 to 100 milliseconds

(Preset value: 25 milliseconds)

4 MONO MOVIE: from 1 to 100 milliseconds (Preset value: 25 milliseconds)

5 ROCK CONCERT: from 1 to 100 milliseconds (Preset value: 15 milliseconds)

6 CONCERT HALL: from 1 to 100 milliseconds (Preset value: 30 milliseconds)

Adjustable.

●By continuously pressing “+” or “–” of theDELAY TIME control, the value changes continuously.

However, the value stops changing momentarily at the preset point.

Note

Adding too much delay will cause an unnatural effect with some sources. Experiment with the DELAY TIME control to create an effect that you find most suitable.
